River Island's director of design shares wedding guest outfit trends

Sian Ryan, the director of design at River Island, shares advice on dressing for weddings all season long. "Before deciding on my wedding guest look, I always consider the dress code - hopefully, this is stated on the invitation, but if not, the design of the invite and choice of venue can give clues about the general vibe of the wedding. I love browsing the likes of Vogue, Who What Wear and Instagram for inspiration," says Sian.

"Whether you like to go all out with vibrant brights or you opt for softer pastel shades, Autumn is the perfect time to experiment with colour. We're expecting yellow in rich mango tones to be a big hit! If such a bold colour is too much of a commitment then consider a more muted shade - I especially love the contrast of pretty, feminine pink in more of an androgynous style such as suiting."

"Of course, you want to look your best at a wedding but it's also important to feel comfortable in what you're wearing. Choosing natural, breathable fabrics such as cotton and silk, especially during these muggier months, means you're likely to be kept cool. A block heel provides the best of both worlds - style and comfort - and is grass-friendly! "

Something less structured means you're more likely to be able to sit down, eat and dance all day long, while evening guests can afford to get a little more slinky and sultry with a show-stopping slip dress. Sian says, "Whether you stay true to your own style by accentuating your favourite features or you use the celebration as a chance to experiment with different silhouettes and styles - my top tip is to have fun with fashion and choose an outfit that makes you feel confident so you can concentrate on having fun!"
